Eddy Current Losses in Conducting Slabs
IEEE Transactions on Power Apparatus and Systems, 1971This paper considers the problem of calculating the eddy current losses in a rectangular conducting slab in a magnetic field which would be uniform if the slab were not present. The length axis is perpendicular to the uniform field, but there may be an angular displacement' about this axis.

Eddy current losses at cryogenic temperatures
IEEE Transactions on Magnetics, 1993The effect of thermal processes on eddy-current losses in the structural elements of cryogenic and superconducting devices are analyzed. Maxwell's equations coupled with the heat-conduction equation are solved, taking into account the dependence of resistivity, heat capacity, and heat-transfer coefficient on temperature.

Intersheet eddy-current loss in laminated cores
Electrical Engineering, 1937CORE LOSS in laminated structures subjected to an alternating magnetomotive force is made up of a hysteresis loss and an eddy-current loss. In modern power transformers the eddy-current loss is approximately 1/4 to 1/3 of the total loss.

Tooth-frequency eddy-current loss
Electrical Engineering, 1937A method of recording, by means of an oscillograph, the eddy currents in various parts of the cross section of a squirrel-cage-rotor bar is presented in this paper. From such records the magnitude of the power loss caused by eddy currents, and its variation with load, may be determined. A series of tests of this nature has been made; the results, which

A New Coil Structure to Reduce Eddy Current Loss of WPT Systems for Underwater Vehicles
IEEE Transactions on Vehicular Technology, 2019Wireless power transfer systems in seawater inevitably suffer some energy loss as a consequence of eddy current loss. Here, we present a coil structure utilizing two transmitter coils placed symmetrically adjacent to each side of the receiver coil.
